While by now most will have dug themselves out from the weekend’s blizzard, there are some winter safety tips to be observed even after the initial excavation.

To facilitate access in the case of an emergency, Greenfield Fire Capt. John Whitney recommends keeping sidewalks and stairs and porches clear and wide and clearing fire hydrants not only to the sidewalk but from the side facing the street as well.

Whitney said he has seen many hydrants cleared on one side only, and it is from the street that firefighters will need to access the hydrants in the event of a fire.

Homeowners should also keep the near-ground vents for boilers and furnaces clear of snow to prevent the potentially deadly buildup of carbon monoxide, and be mindful of the vents as snow falls from roofs.

Residents of buildings with know structural issues should also be careful to clear their roofs, Whitney said, particularly as various weather forecasters predict rain Monday, which could add weight to snow cover.

Clearing roofs should also be undertaken with care. Whitney recommended a roof rake for clearing snow while remaining safely on the ground.

Should it become necessary to clear snowblower blades, first cut the power.

∎ Watch for signs of frostbite: loss of feeling and white or pale appearance in the extremities such as fingers, toes, ear lobes or the tip of the nose. If symptoms are detected, seek medical help immediately.
